Cellular respiration quiz with answers for 8th grade science review

📚 Quick Study Guide

🧬
• Cellular Respiration: The process cells use to get energy from food. Think of it as the cell's way of breathing!
🧪
• Reactants: What goes IN to the process. These are glucose (sugar) and oxygen ($O_2$).
⚡
• Products: What comes OUT of the process. These are carbon dioxide ($CO_2$), water ($H_2O$), and energy (ATP).
🍎
• Formula: The overall equation is: $C_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O + ATP$
💪
• ATP: Adenosine Triphosphate - the main energy currency of the cell.
🌡️
• Location: Takes place in the mitochondria (the powerhouse of the cell!).
💡
• Purpose: To convert the energy stored in glucose into a form the cell can use (ATP).
